Patented Aug. 12, 1930 UNITED STATES THOMAS HAVELOGK KINGSTON, OF WEST SOMERVILLE, MASSACHUSETTS, ASSIGNOR TO BUILDERS? PATENT SCAFFOLDING COMPANY, A PARTNERSHIP COMPOSED OF FRANK G. KINGSTON, A. R. KINGSTON WEST SOMERVILLE, MASSACHUSETTS G. 0., PIlYIlVI, AND MABEL.G. KITCHEN, OF-

rurnoe 1 Application filed March 5, 1929. Serial No. 344,506.

My invention relates to putlogs and an object is to provide a clincher plate connection or attachment with the putlog end which will have in one or another form or embodiment of the invention adaptability or flexibility in application to the putlog and in the performance of its functions without any impairment of that strength and efliciency which are so important because human life'and limb are concerned. 7

My invention consists in whatever is described by or is included within the terms or scope of the appended claims.

In the drawings Fig. 1 is a perspective view of a swiveled type of putlog attachment embodying my in- 'vention;

Fig. 2 is a detail view in vertical section of a clamp used when the attachment is detach-- able;

Fig. 8 is a Vertical section of another embodiment of my invent-ion in which the clincher plate is swiveled;

Fig. 4 is a perspective view'of a fragment or portion of a clincher plate attachment which is non-swiveling.

In all the embodiments of my invention shown in the drawings, the clincherplate is substantially an inverted L-shape and comprises the horizontal blade-like member,'l0,

that is sufficiently thin to be inserted in the joint or space between two bricks in a wall and the vertical shank member, 11, these two members being integral. The brick-engaging or hearing member has as is usual at its outer end a hook, 12, to catch over the inner side of the brick on which the member, 10, rests. Also in each case the shank, 11, is situated between similar brackets, 13, which lie fiat against the shank on each side thereof, the three being rigidly secured together as by rivets, 14. There are thus three plies or layers of metal plates at the shank portion of the clincher which makes an exceedingly strong and rigid construction. Each bracket, 7

there are horizontal outwardly projecting feet. Lying over the feet at the top is a horizontal plate, 16, and extending beneath the feet atthe bottom isa similar horizontal plate, 16, the plate and foot in each case being rigidly united by rivets, 17 I In the embodiment of my invention shown in Figs. 1 and 3 the. clincher plate, 10, is pivoted to swing horizontally, so that the putlog body'which extends from the face ofthe buildingioutward may stand at right angles to such face or at various oblique angles to suit the requirements of the scafiolding having reference to the angular positions of the building walls exemplified in my Patent No. 1,077,839 of November 4, 1913.v To secure that result theupper and lower plates, 16, have'pintles or pivots, 18, that maybe integral with the plate which project through pivot holes in an overlapping plate,19, which constitutes a clip to bear against the top or 'manentlylconnected'with the putlog body.

In this case the device exists in the form of an attachment so that it will be assembled with the proper body at the job, this making foradvantage in shipment or transportation since it makes unnecessary the shipment of the completeputlog including a=bo-dy. For that reason an'inverted: U-sha pe strap or loop, 22, as best shown in Fig.1 is'provided which straddles the-two clips, 19, and is rigidly secured to one of them (top one) by'a rivet, 23; belowthe -other clip, 19, is a crosss-bar, 24:, which at its ends is passed through holes in the legs and the projecting part upset or riveted, and at the transverse center of said cross-bar, 24, is a vertical threaded hole through which passes a clamp screw, 25,

adapted to bear against the underside of the lower clip, 19, and caused to exert a clamping PATENT OFFICE pressure which draws the two clips, 19, with clamping force against the interposed end portion of the putlog body, 20. By unscrewing the clamp screw-25, the pressure is released sufiiciently to permit the withdrawal of the attached device from the putlog body. The clamp screw, 25, has a radial handle, 26, for turning it.

In the embodiment of my invention shown in Fig. 3, the connection between the clips, 19, and the putlog body, 200, is made by a bolt, 27, which passes through avertical hole bored in the body, 200, and through alining holes in said clips, sothat a permanent at tachment of the device to the putlog body may be had.

In the embodiment of my invention shown in Fig. t, the clincher plate is not pivoted or swiveled, but is rigidly fixed in oneposition in which it extends parallel with the length of the putlog body, and the clips, 19, are similar to those of Fig. 1 and a clamping device similar to that shown in Figs. 1 and 2 is employed for the ready detachable connecti on of the device with a putlog. Of course, a permanent connection can be made with the putlog just as is done in the ease of the embodiment shown in Fig. 3.

What I claim is 1. A putlog wall-engaging member having a shank, vertical brackets secured to the shank sides having laterally extending feet, and plates above and below the feet, and connected therewith.

2. A putlog wall-engaging member having a shank, vertical brackets secured to the shank sides having laterally extending feet, and

plates above and below the feet, and connected therewith, and means to securesaid plates to a putlog body.

3. In combination with a putlog wall-en; gaging member, a pair ofopposite clips connected therewith, each clip having a platelike portion to lie upon a side of a'putlog body and flanges to overlap other body sides and means to secure said clips to a body.

4. A utlog wall engaging member having means or attachment to a body comprising opposite body-engaging members, at least one being a plate to lie over one surface of the body, and having marginal flanges to overlap. surfaces of the body at right angles to the plate-engaging surface, and screw clamp means acting simultaneously on said opposite body-engaging members.

In testimony whereof I hereunto aifix my signature.

THOMAS HAVELOGK KINGSTON.
